Rapid baking apparatus for automobile aluminium alloy wheel die

Abstract

A rapid baking apparatus for an automobile aluminium alloy wheel die consists of a workbench, a thermally-insulated shroud, a stainless steel baffle plate, a metal die support disc, a circulating fan, a heating support, an electronic igniter, an antifriction bearing, a circulating fan power supply lead, a thermocouple, a thermocouple lead, a cylinder, a cylinder compression air conduit, an electronic igniter control lead, a natural gas conduit, a compression air conduit, a control cabinet, a temperature display, a natural gas flow control valve, a compression air flow control valve, a cylinder control switch, a circulating fan control switch and an electronic igniter control switch. When in use, the thermally-insulated shroud is opened, a bed die is placed at the center of the metal die support disc, four side dies are pulled open, the heating support is inserted into the antifriction bearing, the thermally-insulated shroud is closed, the igniter switch is turned on, the circulating fan is turned on, the mould is preset with a temperature of 400-450 DEG C, and when the mould reaches the preset temperature, preheating baking is finished. The apparatus has the advantages of being low in cost, convenient to use, rapid in preheating and uniform in baking.

Description

technical field [0001] The invention relates to the field of mechanical equipment manufacturing, in particular to a rapid baking equipment for automobile aluminum alloy wheel molds. Background technique [0002] In the casting process of automobile aluminum alloy wheels, the metal mold needs to be preheated and baked before production on the machine. Whether the preheating temperature of the mold before production meets the process requirements and whether the baking temperature of each area of ​​the mold is uniform will directly affect the surface of the mold cavity. The durability of the coating after spraying the coating, the number of adjustments (that is, casting blanks) during the production process, the appearance quality of the blanks, and the internal casting quality of the castings, so the aluminum alloy wheel metal mold casting is strictly baked and pre-baked according to the process before production. Heat is very important. [0003] At present, there are basica...

Problems solved by technology

[0003] At present, the preheating and baking of aluminum alloy wheel metal molds basically include two methods: preheating and baking in a box-type electric furnace and direct heating and baking on the machine using natural gas. The cycle is long, the energy consumption is high, and the operation is not convenient; using natural gas to directly heat and bake on the machine will cause uneven baking temperature of various parts of the mold, low heat utilization rate, and accelerated aging of casting machine pipes and machine parts, etc. question
